Circumpolar Study of Perfluoroalkyl Contaminants in Polar Bears (Ursus maritimus) [PDF]
Environmental Science & Technology, 2005 Perfluoroalkyl substances were determined in liver tissues and blood of polar bears (Ursus maritimus) from five locations in the North American Arctic and two locations in the European Arctic. Concentrations of perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate, heptadecafluorooctane sulfonamide, and perfluoroalkyl carboxylates with C(8)-C(15)

Prolonged transition time between colostrum and mature milk in a bear, the giant panda, Ailuropoda melanoleuca [PDF]
, 2015 Bears produce the most altricial neonates of any placental mammal. We hypothesized that the transition from colostrum to mature milk in bears reflects a temporal and biochemical adaptation for altricial development and immune protection.
